well look the only thing the kilo lacks that the brougham has are wheels saddle risers and maybe crankset.

if you think you can build a kilo for less that's fine but unless you have a hookup on parts, i really don't think you'll get a great deal. i mean, dp18's and soma low-end components are going to push you to 530 easily and it won't be much of an improvement- and you have a bike with stickers on it.

if you build a frameset from bikeisland you've got 340 dollars more to spend before you get up to the bro, and it's gotta be split between wheels, tires, tubes, cog, lockring, chain, crankset, bb, pedals, seatpost, saddle, collar, headset, spacers, stem, bars and grips. that's a lot to buy. pricing it out at msrp gives you access to clearance low end parts at best, and you have a bike that, while personalized, has to be built up and has no warranty. pressing the headset is the only expensive tool needed but you really don't have room to buy tools in the msrp part list.

i built up my kilo from the frameset a long time ago and it took me four saddles, three seatposts, three stems, two headsets, two cranksets, two wheelsets, and two pedalsets to get it to where i wanted it. i'm not saying i couldn't have done it better the first go around but i will say i spent way more on it than i ever thought i'd spend, or really wanted to put into a kilo.

if i get another fixed gear i'll buy it complete, or spend a fortune on it. and it will either be dura-ace equipped with free shipping, say "tk3" on it, or say "sonik" on it and i'll be rich.
